Difference of squares makes (x+3)(x-3)/(x+3)
The x+3’s cancel out
Answer is x-3
Answer:
95% Confidence Interval = (611.81 ppm, 696.51 ppm)
Step-by-step explanation:
The formula for Confidence Interval is given as:
Confidence Interval = Mean ± z × s /√n
Mean = the sample mean/average = 654.16
s = the sample standard deviation = 164.55
z = z score of 95% confidence interval = 1.96
Confidence Interval =
654.16 ± 1.96 × 164.55/√58
= 654.16 ± 42.348
Hence,
654.16 - 42.348
= 611.812
Approximately to two decimal places = 611.81 ppm
654.16 + 42.348
= 696.508
Approximately to two decimal places = 696.51 ppm
Therefore, the 95% (two-sided) confidence interval for true average CO2 level in the population of all homes from which the sample was selected is (611.81 ppm, 696.51 ppm).
We have to put values of domain to find range
![\\ \ast\sf\longmapsto D_R=[-1,0,1]](https://tex.z-dn.net/?f=%5C%5C%20%5Cast%5Csf%5Clongmapsto%20D_R%3D%5B-1%2C0%2C1%5D)
Now
![\\ \ast\sf\longmapsto R_R=[-2,1,13]](https://tex.z-dn.net/?f=%5C%5C%20%5Cast%5Csf%5Clongmapsto%20R_R%3D%5B-2%2C1%2C13%5D)
It would be corresponding to RG.
